I have an Amtran 2002 t444e and it has the cruise control switches etc but they donít do anything. Iím pretty sure that the cruise is probably just disabled which Iíve heard is common for school buses.

Can I turn it on with a cable and software or something myself? If so what cable/software do I need?

Or should I just take it to a dealership? If itís not too expensive or difficult Iíd prefer to do it myself...

yeppers the others have it right, its an option most often disabled by the schools and easy to turn on... post where you sre at, there may be a fellow skoolie with the compouter interface nearby.. navistar gives away the Level 1 version of the software (servicemaxx J170 which you can enable it yourself, however you need the RP1210 interface box which is not cheap (even the knock-offs)..

finding someone to turn it on for you is likely the easiest for you unless you want to own the scan tools for future diagnosis and such

marc, turn your cruise control main switch to ON , then try revving the engine with the pedal in neutral to where you want, then press 'SET' or you can hold down the resume / accel and it should slowly speed up the engine.

When I get it running I'll give that a try. Makes sense, though I thought it had a set high idle speed. Thanks
